| Outline of Final Research Achievements |
We estimate structural demand-supply models to evaluate the diffusion effect of the buyback subsidy and the feed-in tariff (FIT) for the residential-use photovoltaic (PV) systems in Japan. We found that the subsidy program boosted PV installation more than 30% and the FIT also prospected to accelerate future installation under the condition that future buyback prices of electricity would be kept high enough as well as sufficient cost reduction of PV would attained. These diffusion policy, however, do not make sense with respect to the social welfare unless we assess the economic value of the reduction of greenhouse effect gas much more than its market value and/or social cost estimated.
